That document says to me, at least, that 'short rotation coppice' is taxable. The 'short rotation' term is defined as under 10 years.
The rest, however, to me, is clear as mud! Too many acronyms for someone who doesn't fill out a self-assessment tax form.
Also worth bearing in mind is that the document dates from June 2004, so may be out of date? I thought I read somewhere once that timber was treated differently to coppice for tax purposes and the article specifically says (misleadingly, IMO) that short rotation coppice = the quick production of timber. Leaving aside that a minimum of 10-12 years for the quickest-growing trees, is hardly quick in economic terms, I don't think much in the way of "timber" would be produced by short rotation coppice, would it?
Oh god, I've just realised that this leads to another one of my "simple" questions - how do you define 'timber' - for tax purposes - and if you like, for fun, in woodlands-owner speak?! [sorry!].
